Exchanging information securely using quantum communication in future fiber-optic networks

Searching for better security during data transmission, governments and other organizations around the world have been investing in and developing technologies related to quantum communication and related encryption methods. Researchers are looking at how these new systems -- which, in theory, would provide unhackable communication channels -- can be integrated into existing and future fiber-optic networks.
